This research introduces an efficient and new multicast congestion
newlinecontrol algorithm for asymmetric paths with improved Round Trip Time
newline RTT calculation In the current Internet scenario streaming applications
newlinebecome popular and which use multicast approach Congestion control in
newlinemulticast protocol is a difficult task and lot of research is going on in this area
newlineTo enhance the bandwidth utilization instead of symmetric path an
newlineasymmetric path is a viable alternative But the existing algorithms are not
newlinedirectly applicable for such application In this thesis we propose a new
newlineprotocol in which the receiver explicitly adjusts its reception rate according to
newlinethe network conditions using TCP throughput equation and Packet Pair probe
newlineIts effectiveness has been checked by using simulation techniques The most
newlinepopular network simulator ns 2 is used in this analysis
newlineCongestion is the major problem in the Internet multicast There is
newlinea growing set of non TCP applications such as Internet audio players IP
newlinetelephony video conferencing and bulk file transfer which are generally
newlinecalled as multicast applications So far there have been three directions of
newlinemulticast congestion control proposed namely sender driven router based
newlineand receiver driven Out of these receiver driven with multi rate is more
newlinesuitable for today s Internet called Multi Rate Multicast Congestion Control
